Problems solved by technology

[0006] A technical problem with existing heat exchangers is that while the fins provide enhanced heat transfer and added structural advantages, the fins also increase resistance to the flow of the second fluid moving within the channels, resulting in wall shear

Embodiment Construction

[0022] Embodiments of the subject matter described herein relate to thermal management systems (eg, heat exchangers) and methods that include a plurality of fluidly separated tubes that are wound around each other and extend along a tortuous path between a first end and a second end . The coiled tubing guides through the system a first fluid that exchanges thermal energy with a second fluid within the channels of the system. For example, a coiled conduit may have a tortuous path between a first end and a second end of the conduit. The tortuous path of the conduit increases the surface area of ​​the conduit to interact with the second fluid within the channel, thereby controlling the amount of thermal energy transferred between the first fluid and the second fluid. The system may include one or more arms extending between one pipe, and / or one or more arms extending between two or more different pipes, to maintain the distance between the first end and the second end of the pip...

Abstract

A thermal management system includes a body having an inlet and an outlet configured to direct a first fluid into and out of the body. The body includes a channel fluidly separated from the inlet and the outlet. A second fluid is directed through the channel. A conduit assembly is fluidly coupled with the inlet and the outlet. The conduit assembly includes a plurality of fluidly separated conduits. Each of the plurality of conduits extends along a respective tortuous path between a respective first end and a respective second end. The plurality of conduits are intertwined between the first end and the second end. The plurality of conduits are positioned to cause the second fluid flowing through the channel to flow over the plurality of conduits and exchange thermal energy with the first fluid moving within each of the plurality of conduits.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to Indian Application No. 202011029731, filed July 13, 2020, and US Patent Application 17 / 369,468, filed July 7, 2021, the entire disclosures of which are incorporated herein by reference. technical field [0003] The described subject matter relates to fluid thermal management systems and methods. Background technique [0004] Heat exchangers such as radiators may contain oil, water and air as cooled or heated working media. For example, heat exchangers may be used with engines to transfer heat between different bodies or volumes. For example, a first fluid with a relatively high temperature may pass through a first channel, while a second fluid with a relatively low temperature may pass through a second channel. The first and second channels may be in thermal contact or in close proximity, allowing heat to be transferred from the first fluid to the second fluid. Thus, the temperatu...
